MOUNT LASSEN, CALIFORNIA, 
IN ERUPTION JUNE 14, 1914

CALIFORNIA 

From San Diego, where the first of the Franciscan 
Missions was established, to Mount Shasta, which 
dominates the entire northern section of California 
and is the most perfect mountain along the whole 
thousand miles of the Sierra Nevada, what a rare 
variety is here of cloud-capped mountain peaks, tur¬ 
quoise blue lakes, butting crags, giant Sequoia forests, 
fertile foothills, enormous valleys and rugged coast, 
pierced by the entrance to the one great harbor on 
the entire Pacific Slope. No parallel can be found 
for it in this country, nor even abroad ; for a half 
day’s journey will carry the tourist from the ever¬ 
lasting snows in the high Sierra to the burning heat 
of the great valleys. The Alps are well called the 
playground of Europe, but here in this single state 
are gathered beauties that far outstrip all that Switzer¬ 
land has to offer. 

—George Hamlin Fitch. 


© here is no other land so lovely, so con¬ 
stant, so generous. It lies between the 
desert and the sea—God’s two sana- 
toriums for weary flesh and weary mind. The 
Sierra’s eternal snows, the desert’s clean, hot 
breath, the ocean’s cool winds and the warmth 
of the sinuous current of Japan winding 
through it, all combine to make a climate 
hopelessly unrivaled by even the most favored 
shores of the Mediterranean. It is a land of 
artist’s dreams, endless with flower-flamed up¬ 
lands, swinging lomas and majestic mountains. 
It changes with every color of the day and is 
soft and sweet unspeakably under low-hang¬ 
ing stars and great, shining moons. 

There is not anywhere a valley to rival the 
beauty of Yosemite, or the fruitful area of the 
San Joaquin; the most splendid harbor in the 
world is the Bay of San Francisco; the Mari¬ 
posa Sequoias are the largest trees in existence 



AVENUE OF FAN PALMS, MISSION SAN JOSE 




as they are also the oldest living things on the 
face of the earth. Never was there a road more 
glamorous with romance or more eloquent 
with service than El Camino Real on which 
still linger the gray ruins of the old Francis¬ 
can Missions. Southward wind still the brown 
trails of the Padres, northward are the hills 
from which the Argonauts wrung the most 
stupendous cache of gold that Nature had 
ever hidden away. 

If you were to spend a year of happy wander¬ 
ings between San Diego’s harbor of the sun 
and the valley of the Seven Moons, and then 
another summer still till you reach the trails 
that lie under Shasta across the hills of Del 
Norte, Modoc and Siskiyou, then would you 
know with what tenderness God has fashioned 
California. Always from the Wander Trail 
would your eyes behold the glory of the sea, 
the soft purple of dreamy isles, sun and shine 
to light your feet by day and the wonder of 
the stars to cover you at night. 

—John Steven McGroarty
